AUTHCONFIG(8) System Manager's Manual AUTHCONFIG(8) NAME
authconfig - an interface for configuring system authentication resources SYNOPSIS
authconfig [--back] [--test] [--nostart] [--kickstart] [--probe] [--enablecache] [--disablecache] [--enablenis [--nisdomain <domain>] [--nisserver <nisserver[,nisserver...]>] ] [--disablenis] [--enableshadow] [--disableshadow] [--enablemd5] ] [--disablemd5] ] [--enableldap [--enableldapauth] [--enableldapssl] [--ldapserver <ldapserver>] [--ldapbasedn <basedn>] ] [--disableldap] [--disableldapauth] [--enablekrb5 [ --krb5realm <realm> ] [--krb5kdc <hostname[,hostname,...]>] [--disablekrb5] [--krb5adminserver <hostname[,hostname,...]>] ] [--enablehesiod [--hesiodlhs <lhs>] [--hesiodrhs <rhs>] ] [--disablehesiod] [--enablesmb [--smbworkgroup <workgroup>] [--smbservers <server[,server]>]] DESCRIPTION
authconfig provides a simple method of configuring /etc/sysconfig/network to handle NIS, as well as /etc/passwd and /etc/shadow, the files used for shadow password support. Basic LDAP, Kerberos 5, and SMB (authentication) client configuration is also provided. The authconfig window contains a Cancel button by default. If --back is specified at run time, a Back button is presented instead. If --test is specified, authconfig can be run by users other then root, and any configuration changes are not saved. If --nostart is specified (which is what the install program does), ypbind will not be started or stopped immediately following program execution, but only enabled to start or stop at boot time. if --kickstart is specified, no interactive screens will be seen. The values the program will use will be those specified by the other options (--enablemd5, --usehadow, etc.). The --enablenis, --enableldap, and --enablehesiod options are used to configure user information services in /etc/nsswitch.conf, the --enablecache option is used to configure naming services caching, and the --enableshadow, --enablemd5, --enableldapauth, --enablekrb5 and --enablesmb options are used to configure authentication functions via /etc/pam.d/system-auth. Each --enable has a matching --disable option that disables the service if it is already enabled. The --probe flag instructs authconfig to use DNS and other means to guess at configuration information for the current host, print its guesses to standard output, and exit. The default in kickstart mode (i.e. without any additional options) is to not change the current settings. RETURN CODES
authconfig returns 0 on success, 2 on error, and 1 if the user cancelled the program (by using either the Cancel or Back button). FILES
/etc/sysconfig/authconfig Used to track whether or not particular authentication mechanisms are enabled. Currently includes variables named USESHADOW, USEMD5, USEKERBEROS, USELDAPAUTH, USESMBAUTH, USEHESIOD, USENIS, USELDAP. /etc/passwd, Used for shadow password support. /etc/yp.conf Configuration file for NIS support. /etc/sysconfig/network Another configuration file for NIS support. /etc/ldap.conf /etc/openldap/ldap.conf Used to configure LDAP (and OpenLDAP, respectively). /etc/krb5.conf Used to configure Kerberos 5. /etc/krb.conf Used to configure Kerberos IV (write-only). /etc/hesiod.conf Used to configure Hesiod. /etc/pam_smb.conf Used to configure SMB authentication. /etc/nsswitch.conf Used to configure user information services. /etc/pam.d/system-auth Used to configure PAM for system services via pam_stack(8).
